Fair enough, anyway the overall SNR for the Essence STX is 124dB, so it's limited by something other than the DAC, so upgrading the DAC probably wouldn't have a significant effect. And upgrading the supporting circuitry to allow an overall SNR of (approximately) 130dB would probably make the card unreasonably expensive. The "best of the best" DAC would've been nice for bragging rights, but otherwise wouldn't make a whole lot of difference.
I didn't mean disparage the D2 DAC's - until the Essence STX came along they were best DAC's on any consumer sound card, and they're still better than the DAC's in many (most? all?) low and mid range pro-audio cards. The D2 supports 7.1 channel audio, so it needs 4 DAC's and their supporting circuitry; whereas, the STX is stereo and thus only requires a single DAC. A 7.1 channel card using the same DAC's and (expensive) supporting circuitry as the STX would be horrendously expensive. I meant it as an example of how high-end the STX DAC's are, and to illustrate how insignificant $1.20 would be compared to the difference in price between the D2 and STX DAC's.
The Essence STX is pretty much perfect for me: I use hifi headphones on my computer, so I have no need for 7.1 channel support, and at the same time I can take full advantage of high quality stereo output. Furthermore, I've been looking for a good soundcard or external DAC box for awhile now. So the STX is at the top of my personal computer hardware wish list.
